m68k: apparently, the right place for the sar qword helper is still in the CPU include, not the 64bit helper include. this fixes linux m68k build.

m68k: clear the FPU Control Register at program start. This fixes some testcode randomly failing on AmigaOS, where the FPCR state is inherited from the parent task. Also added the FPCR layout and rounding modes info, based on the Motorola 68k PRMm68k.inc
